After showing in public a few times already MorphOS running on PowerBook G4 (video on YouTube) and on PowerMac G5 (AVI video), today one of the core developers has released a few screenshots (1, 2, 3, 4) of MorphOS running on an iMac G5 20" clocked at 2.1GHz and equipped with a Radeon X600 graphic card.
As usual, no promises, let alone a release date, have been given.
